Re: Ethereal items with charges...repair?
Actually, it's not as simple as that (edit: referring to gbones' post, not olbaid's). HoW is off-weapon damage, while etherealness is on-weapon damage. On-weapon damage is better (though I'm much too lazy to figure out the balance points). Also, the spirit will get killed by monsters. Quite often. And it'll definitely die every time the you get stuck fighting a group of really tough enemies (so when you want it the most, it's virtually guaranteed to get killed)...
... The AR boost is nice though.
But I'd take the ethereal Oath in a heartbeat.
